Application filed March 9, 1917, Serial No. 153,589. Renewed February 26, 1220. semi No. 361,412.

To aZZ whom it may concern Be it known that we, Ross (1,002; and Jor-nv F. MGGINNITEY, citizens of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented certain useful Improvements in Washing and Mixing Wachines. of which the following is a specification, reference being had therein to the accompanying drawin The invention relates to a mashing and mixing machine, and more particularly to the class of foodstuff mashers or mixers. I

The primary object of the invention is the provision of a machine of this character wherein potatoes, turnips, squash, carrots and other foodstuffs can be thoroughly mashed and'mixed or the machine may be used for beating eggs, whipping cream or making butter, as well as for mixing dressings or sauces.

Another object of the invention is the provision of a machine of this character wherein the heaters or mixing elements are operatecL in opposition to each other and can be driven at the desired speed for the proper mixing or mashing of materials with despaech and the mashing and beating of such materials is effected in a sanitary way so as to avoid lumps and will render the material fluffy as the saline will be thoroughly whipped for assuring lightness.

A further object of the invention is the provi ion of a machine of this character wherein the materials can be maintained hot and on operating the machine such materials mashed or thoroughly mixed without possibility of rendering such materials soggy and lumpy.

A still further object of the invention is the provision of a machine of this character wherein the parts are readily accessible so that the machine can be thoroughly cleaned to assure it being sanitary.

A still further object of the invention is the provision of a machine of this character which is simple in construction, thoroughly reliable and eflicient in operation, strong, durable and inexpensive in manufacture.

Other objects will be in part obvious and in part hereinafter set forth.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts Which will be exemplified in the construction hereinmounted on a the body 10 exterioriy thereof, and

stud which nine-a ta) after described, and the scope f the pplication of which will be indicated in the ap- Fig. 3 is a vertical longitudinal sectional view;

11g. 42 is a vertical transverse sectional view.

Similar reference characters indicate co"- responding parts throughout the se views of the drawing. 7

Referring to drawing in detail, the

V

Journnled in opposite ends of the body 10, cent ily thereof, a iongiudinal shaft 15 which has one end extended externally the body, and this extended end las thereto a pinion i6 with which meshes a driven gear 17 journaicd upon a stud bracl t fixed to one end of this 1 upon a the end of the body 10 spaced from the stud 1b, and this pinion 20 has connected thereto operating handie so that on turning the pinion 20 motion wiil be imparted through the gear 21 to the pinion 16 for rotating the shaft 15 in one direction.

The pinion 20 has formed in 23 which meshes with a pinion meshes with a pinion 29 journal (J8 shalt iy 10,

Each beater frame comprises end bars 28 and longitudinal rails 29, the latter being square in cross section throughout'a major portion of their length, while the ends are reduced and rininded at 30 to ti t within end bar. 28 and are secured thereto so as to term the rigid beating frame. The shaft 15 on that portion which is comprehended be tween the ends ol the l: ne 2? is also squar in cross section.

Further, the rotation ot'the shaft 'in'one direction and the rotation oi. the

frame in the opposite direction result at onetime inbringing the fiat s1des of the shaft opposite the corners o'l the rails 29 of the frame and at another time in bringing thecern'ers oil: the shairt opposite This operation resul's in a variation of the width of space between the shaft and the rails of the frame 27 at different positions during their relative movement. 'lhereliore lumpy portions of the substance or n'iaterial being mashed, finding their way between the shaft and the rails of the frame 27, are crushed between the rails and the corners of the sha-ft.
